In the reported experiments of McLean and Hastings, their equation was found to be valid for predicting the calcium ion concentration from the total calcium and total protein when the sera contained 7.5 grams of protein per 100 cc. or less. It has recently been shown by Gutman and Gutman (3) that serum from cases of hyperglobulinemia had less total calcium than one would have expected, if the c...

BACKGROUND Type 2 diabetes mellitus (T2DM) is a recognized trigger factor for heart failure with preserved ejection fraction (HFpEF). Recent studies show that higher serum calcium level is associated with greater risk of both T2DM and heart failure. We speculate that increased serum calcium is related to HFpEF prevalence in patients with T2DM. METHODS In this cross-sectional echocardiographic...

Total serum calcium levels were measured in 12 865 men and 14 293 women, between the ages of 25 and 97 years, in the Tromsø Study during 1994 and 1995. With the use of a sex-specific multiple linear regression model with age, calcium, body mass index, cholesterol, HDL cholesterol, triglycerides, systolic and diastolic blood pressure, and pulse as possible covariates, serum calcium was significa...

INTRODUCTION Recent epidemiological evidence suggests that alteration in calcium, phosphorous or magnesium metabolism may have direct cardiovascular consequences. However, it is unknown whether variations in serum values of these minerals are in relationship with lipid profile and adiposity as metabolic risk factors of cardiovascular events in premenopausal women independent of confounders. The...

BACKGROUND Several studies have focused on the effects of calcium intake on serum lipid concentrations in postmenopausal women. However, many premenopausal women are taking calcium supplements in China. To our knowledge, no studies have assessed whether the effects of calcium supplementation on blood lipids are similar between premenopausal and postmenopausal women. OBJECTIVE We assessed the ...

Total serum calcium, its fractions and serum citrate concentrations were measured in children receiving massive blood transfusion for scoliosis surgery, and in other children undergoing open heart surgery with cardiopulmonary bypass. During scoliosis surgery, although up to 100% of blood volume was replaced, and no additional calcium salts were infused, serum ionized calcium concentration remai...

The sunlight has an important role in metabolism of calcium ( Ca) and phosphorus ( P). The sunlight has different effects in different places. Therefore  the pattern of metabolic disease depends upon geographical place. In this investigation two groups of workers( one group working in shadow and the other under the sunshine) were chosen as control and experimental groups respectively.these two ...

Total serum calcium levels were measured in 12 865 men and 14 293 women, between the ages of 25 and 97 years, in the Tromsø Study during 1994 and 1995. With the use of a sex-specific multiple linear regression model with age, calcium, body mass index, cholesterol, HDL cholesterol, triglycerides, systolic and diastolic blood pressure, and pulse as possible covariates, serum calcium was significa...

1. Ionized calcium, protein-bound calcium and total calcium in serum were measured in patients receiving haemodialysis treatment. 2. During dialysis, the ionized calcium fraction decreased and the bound calcium increased. The blood pH also increased. 3. Studies in vitro suggested that the fall in ionized calcium and rise in protein-bound calcium were larger than could be explained by the redist...

Background and aim: Side effects of long-term systemic isotretinion use with high accumulative doses on skeletal system have been known, but there are few studies about the effects of short term isotretinoin therapy for acne patients. This study was aimed to recognize the effects of systemic isotretinion on calcium homeostasis and bone density in acne patients referring to clinics affilia...
